Setting the baudrate
Adjusting the control head to the baudrate of the network.
Dip 7 Dip 8 Baudrate
off off 125 kbaud
on off 250 kbaud
off on 500 kbaud
on on not permitted
Table 16: Setting the baudrate
please note: if the settings are changed by actuating the Dip switches, this change will not take
effect until the device is restarted.
For a restart
• briefly disconnect the control head from the power supply and reconnect or
• switch the power supply off/on or
• transmit an appropriate reset message.
11.10 configuration of the process data
To transmit process data via an I/O connection, 1 static input and 1 static output assembly can be selected. These
assemblies contain selected attributes combined into one object so that process data can be transmitted collectively
via an I/O connection.
Process data can be accessed
• cyclically in the connection variants “Polled I/O” and “Bitstrobed I/O”, with “Change of state”, if input values
change, or
• acyclically via Explicit Messages.
The access path for acyclical access is:
class 4
instance 1
attribute 3
With the
Get_Attribute_Single service the input data can be accessed acyclically for reading.
With the Set_Attribute_Single service the output data can be accessed acyclically for writing.
